Linux CacULE (feedback & testing)

And its running ? :smiley:

103

Me?

The latest version with dragonized/test does not run on my particular old Nvidia machine. I also don't have that much time to research the causes.

My next computer is Nvidia free. :smiley:

Sorry for offtopic: If I buy full AMD laptop, how to switch AMD iGPU and dGPU?

Maybe, but then, many have tested Linux Cacule here. So, this is issue with my hardware, I guess. Not sure tbh. Maybe I have to compile it myself for my hardware.

:thinking:

There should be a more easier solution then with nvidia

Let know me... I can try find really old piece of hardware at my job and try linux-cacule.

I went ahead and compiled linux-cacule yesterday.

So far, system responsiveness seems to better. What I've really noticed is an ability for much more intensive tasks to run at once.

For example, I am compiling linux-cacule again right now, and I am using a web browser without it being a laggy mess. That in itself, I have never seen before.

There are only one minor problem I have, but it just has to do with the compilation process.
The current PKGBUILD only makes the package with 1 thread. I went in and manually specified using the -j12 flag.

@ptr133, assuming it is permitted in the AUR, there is a way to dynamically determine the number of threads and then specify it as a build flag.

One example I found is in the PKGBUILD for linux-tkg:

 _force_all_threads="-j$((`nproc`+1))"

#applied to linux-cacule build step
make ${_force_all_threads} all

For more info on this, refer to the code around line 544 in the PKGBUILD: linux-tkg/PKGBUILD at master Ā· Frogging-Family/linux-tkg Ā· GitHub

Normally you specify the number of threads in /etc/makepkg.conf and not in the PKGBUILD, unless the latter has !buildflags option.

This is normally done automatically via a pacman hook, on my system itā€™s /usr/share/libalpm/hooks/90-mkinitcpio-install.hook which calls the mkinitcpio-install script.

The GRUB hook might be missing on some systems, you can create it manually, e.g.

[Trigger]
Type = File
Operation = Install
Operation = Upgrade
Operation = Remove
Target = usr/lib/modules/*/vmlinu*
Target = boot/vmlinuz*

[Action]
Description = Updating Grub Menu
When = PostTransaction
Exec = /usr/bin/grub-mkconfig -o /boot/grub/grub.cfg

Apart from me not doing any gaming (thus not being able to judge FPS etc) this is what I also observed using this kernel. Really gotta love full load behaving responsive on a rather low end device. :innocent:

In fact I also only recently learned there is such a file :laughing: You can set a lot of other options there such as compiling packages for your specific hardware (march=native). It might be a good idea to inform users about setting this up, maybe in the wiki?

I have next thing for you what I learned form @ptr1337
Edit your makepkg.conf for faster compiling
sudo nano /etc/makepkg.conf

MAKEFLAGS=ā€œ-j$(nproc)ā€

Garuda/Arch will use all CPU cores for compiling!

there are also other ways to speed up compile times in the arch makepkg wiki.

@ptr1337 Did you remove the localmodconfig option from the PKGBUILD?

Me! :laughing: Itā€™s so comfortableā€¦

Thank you bro :muscle:

Edit: @ptr1337 Iā€™m actually using the RDB version. I tried to use it a few days ago with no success (it didnā€™t even boot). Now it works for me andā€¦ Thatā€™s brilliant. I can play xonotic with ultra settings and FPS are always stacked to my monitor refresh rate. No FPS drop. Itā€™s the first time I can do this.

Ah, Iā€™m using 2000 Hz option: the system is flying.
